Introduction: , a genus with rich morphological and ecological diversity in Bionectriaceae, has a wide distribution among diverse habitats.

Methods And Results: In the present study, a phylogenetic framework is reconstructed for the family Bionectriaceae focusing on through increased taxon-sampling using the nr sequence. Through surveying in China, Vietnam, and Thailand over the past 3 years, seven spp.

The current study was aimed to introduce five new species of from Yunnan, with morphological descriptions, illustrations, color photographs, phylogenetic placement, associated host, and a comparison with allied taxa. The five new species were morphologically distinct from all other species, and it was also suggested that they should differ from other species in the genus based on combined multigene analyses. Employing DNA nucleotide sequences of the nr, nr, α, , and , the five new species were recognized in the clade of by using molecular phylogenetic analyses, including five well-supported subclades: three new species, , and , were found in the subclade of , and two new species, and , were located in the subclade of .

A new fungus, , parasitic on the larva of Noctuidae (Lepidoptera) was identified from a survey of entomopathogenic fungi in Kunming Wild Duck Forest Park, Yunnan Province, China. It can be primarily distinguished from relatives by its longer fertile parts, sterile tips, superficial perithecia, narrower asci, and smaller septa of ascospores. As revealed from phylogenetic analyses inferred from nrSSU, nrLSU, tef-1α, rpb1, and rpb2 sequence data, belongs to the clade in the genus of Ophiocordycipitaceae, and forms a separated clade from other related species.

Cordyceps militaris is a traditional Chinese medicinal food that is challenging to quality maintaining while mass cultivation. Many studies have found that abundant microbes inhabit Ophiocordyceps sinensis and perform important functions for their host. In this study, our objective was to reveal the microbial communities that inhabit C.

Background: Some species of Cordyceps sensu lato are famous Chinese herbs with significant biological activities, often used as edible food and traditional medicine in China. Cordyceps represents the largest entomopathogenic group of fungi, including 40 genera and 1339 species in three families and incertae sedis of Hypocreales.

Objective: Most of the Cordyceps-derivatives have been approved clinically for the treatment of various diseases such as diabetes, cancers, inflammation, cardiovascular, renal and neurological disorders and are used worldwide as supplements and herbal drugs, but there is still need for highly efficient Cordyceps-derived drugs for fatal diseases with approval of the U.
